I have this bit of code in my dll:

and here is the code in dbp

when I try to compile dbp app, i get the error:
"User function 'print text' must return a value if used in an expression at line 1"
I checked the string in the dll using notepad and used the new decorated string in the .rc file.
If I call the other example function GET VALUE, it returns value just fine without error.
What am I missing here?

p.s. this is just a practice dll to get the hang of interacting with dbp.

What does your string table look like?

String tables wrong, for your print text command it should be:

IDS_STRING102 "PRINT TEXT[%LS%?PrintText@@YAHPAD@Z%String"

If you're returning a value then you need a [ before the first % and the first letter in the parameter type list should be the return value type.
